SPECIFICATION forming' part of Letters Patent No. 226,093, dated March30, 1880,

Application iiled January 19, 1880.

To all whom 'it may concern:

Be it known that I, WILLIAM ScoBIE Mc- LEOD, of Kingsville, in thecounty of Essex and Province of Ontario, in the Dominion of Canada, haveinvented certain new and useful Improvements in Pumps, of which thefollowing is a specification.

My improved pump is specially designed for use at will as a surface orsuction pump, or be submerged in a well, cistern, or reservoir, or usedin a portable tank, and as a doubleacting pump for raising water fromdifferent wells or cisterns and discharging the same in one or morestreams, and to4 this end the invention consists in a pump cylinderdivided into two chambers, in the Lipper one of which the piston isadapted to work with induction and eduction side pipes, connected toeach end of the upper chamber by horizontal reversible valved sections,the induction side pipes being connected with the lower'chamber bymeansof nonvalved sections, the lower ends of the pump-cylinder and inductionside pipes being provided with bottom and side openings andinterchangeable plugs and valved sections, whereby the valve-ports maybe changed to adapt the pump to the different kinds of work required.

In the accompanying drawings, Figure l represents a vertical section ofa pump embracing my improvements, said section being taken through theinduction side pipes, and the pump being shown for surface or suctionuse in a well, the cylinder communicating therewith by a valvedconnection at its lower end; Fig. 2, a similar section, the lower end ofthe cylinder being closed and the induction side pipes communicatingwith separate wells or cisterns, the pump being shown for surface orsuction use above the wells or cisterns Fig. 3, a similar section,showing the pump as used with an inclosing portable tank for submergedaction, the lower ends of the cylinder and of the induction side pipesbeing closed and the side plugs of said induction-pipes removed, saidpump being also thus used in a cistern or well with the openings eclosed and the top openings, e2, open Fig. 4, a similar section takenthrough the eduction side pipes with the pump used as in Fig. l, andFig. 5 a horizontal section through the upper valved connections of theinduction and eduction side pipes.

The pump-cylinder A is constructed of any suitable material, and isprovided 4with a piston, B, and a piston-rod, C, the latter extendingthrough the head of the cylinder and connected with an operating-lever,I), fulcrumed to the pump or some other suitable support.

The pump-cylinder is provided near its lower end with a partition, E,dividing it into an upper and a lower chamber, which are connected withinduction side pipes, F, at three points, two aboveand one below thepartition E, by means of short removable tubular sections Gr H, thesections G Gr being provided with valves g, and the sections H H arewithout valves in the lower chamber, d', for the purpose hereinaftermore fully set forth.

The induction-pipes F, near their lower ends, are provided with sideopenings, e, which may be closed with plugs I, and the upper ends oi'said pipes F are also provided with similar plugs K, which lcan beinserted or removed to change the operation of the pump.

The pump-cylinder and inductionpipes, at their lower ends, are providedwith removable valved sections M M and removable plugs M3, by means ofwhich the pump may be adapted to the different kinds of work required.The pump -cylinder is provided, also, with vtwo eduction-pipes, N, whichare connected with said cylinder at each end of the upper chamber, d,thereof by means of removable sections O, which are provided with valvessimilar to the sections G. Each of the eduction-pipes is provided withan opening, I), for the discharge of water, and air-chambers Q, thedischarge-opening having a discharge-spout, q, to which a hose may beattached for throwing water in any direction.

The removable valve-sections are provided with suitable packing-rings,bymeans of which water-tight joints are formed, and the pumpcylinder andinduction and eduction pipes are held together by means of the clamps S,provided with the clamping-screws T, by means of which they can betightened upon the parts to be held together.

When the pump is to be used as a surface lifting and force pump theplugs I are inserted in the openings eof the induction-pipes, as arealso the plugs K and Min the upper and lower ends of said pipes, as inFig. 1. The valvesections G of the induction-pipes F are arranged withthe valves g g opening into the pump-cylinder, and the valve-sections Oof the eduction-pipes N have their valves g opening into the said@duction-pipes, as shown in Figs. 4 and 5.

The lowerend of the pump-cylinderis titted with its valved section M,and this section is attached to the suction pipe extending into thewell, cistern, or reservoir. Upon operating the piston, as shown in Fig.l, the valved section M is used, the induction -pipes being closed bythe plugs M3 and I, and water will be taken into the cylinder, passingfirst into the lower chamber, d', of the same, then alternately intoeach end of the upper chamber, d, through the valved sections G H of theinduction-pipes F, and inally out through the valved sections O of theeduction-pipesN and the discharge opening or openings, as shown by thearrows, Figs. l and 4.

When desired to employ the pump submerged, all the lower openings of thepumpcylinder and induction-pipes are closed and the plugs K removed 'andthe pump placed in a well, cistern, or reservoir. The piston-rod is thenconnected with suitable mechanism at the surface for operating it, andthe water surrounding the upper part of the pump will be taken inthrough the top openings, e?, in the induction-pipes, and will followsubstantially the same course as above described.

Vhen it is desired to employ the pump for raising from separate wells,cisterns, or reservoirs, the plugs I are inserted in the side openings,e, and the plug M3 in the lower end of the pump-cylinder. TheValve-sections M', being in the lower ends of the induction-pipes, areconnected with suitable suction-tubes leading to di'erent wells orcisterus, as in Fig. 2, and upon operating the pump the water will bedrawn into the pump from each well or cistern and discharged from theopenings in the eduction-pipes in sepa-rate streams. If desired todischarge in a single stream, it is only necessary to stop one of thedischarge-openings P.

rlhe valves c of the sections Ml serve to prevent the water from fallingback into the cisterns from the pipes F at the moment the motion ofthepiston is changed at each end of its stroke, at which point the pistonfor an instant is virtually at a stand-still. The said valves also serveto keep the pipes full of water when the pump is idle, so that it willcommence operation at once when started, and there will be no delayconsequent upon the necessity of drawing water from the wells to illsaid pipes at the starting. The same function takes place with thevalved section M of the cylinder, although it will be seen that thesevalves e' are perpetually open when the pump is in operation. They donot open and close with the up-and-down stroke of the piston, but areonly employed to keep the pump charged with water at all times.

It will be seen from the above description that a pump having thecapacity of four ordinary pumps can be compact-ly formed and secured ina box or casing, which may be mounted on rollers or wheels and used forhousehold, farm, garden, or domestic purposes, or in case of fires. Thewhole may be made of wood except the caps ofthe air-chambers, piston,and bolts, the wooden parts being soaked in hot oil, which will renderthe pump more durable and cleanly.

By varying the positions of the interchangeable valved sections othercombinations may be made, by which the capacity of the pump may befurther increased. For instance, the valved sections G ot" one of theinduction-pipes may be arranged to open into the pump-cylinder and thevalves of the other out of the same into the opposite induction-pipe,the plug K at the upper end of one pipe being removed, and at the otherpipe the plug is replaced by a pipe leading to an air-chamber anddischargeopenings. By reversing the valve-sections the pump can bechanged from suction to force.

The pump, as above constructed with the various openings and removablevalve-sections and removable plugs, can be easily converted into anordinary force-pump or double-acting lifting or force pump, and can beadapted for use as a surface pump or submerged pump or a portablegarden-pump by making the proper changes or' the parts, which can bereadily made, and the whole, by suitable packings, bound together in acompact and water-tight condition of the joints.

In using the pump with a portable tank the bottom of the tank isprovided with a anged bottom, with openings for the lower end of thepump-cylinder of the induction-pipes, which openings must be suitablypacked, as in Fig. 3. A separate head may be used in the bottom of thetank for this purpose', as shown.

In Fig. 6 I have shown in section the airchamber and a section whichconnects with the top planking of the well by a flanged base, and foruse as a submerged pump, in which the water is taken in through the topopenings, e2, all the lower openings being closed by the plugs M3 and I.

I claim- 1. The combination of the pum p-cylinder, divided into twochambers, d d', by a partition, E, near its lower end, its piston andinduction and eduction ports, with the induction-pipes, provided withside openings, e, having removable plugs I, and the lower ends of thepumpcylinder and the lower and upper ends of the induction-pi pes F,provided with interchangeable plugs and valved sections, whereby thepump may be adapted as a surface-pump or a submerged pump at will,substantially as specied.

2. The combination, with the pump-cylinder' and the induction-pipes F,connected thereto, as described, of the eduction-pipes N, connected withthe upper chamber, d, of the pumpcylinder by means of reversiblevalve-sections IOO IIO

IZO

G, and the interchangeable plugs and Valved sections of thepump-cylinder and inductionpipes, whereby water may be lifted from twocisterns or reservoirs and discharged in single -or separate streams,substantially as specified.

3. In combination with the pumpcylinder. its induction and eductionpipes F and N, the reversible valve-sections G, whereby the ports of thepump-chamber may be changed at will to adapt the pump to different uses,as specified.

4.
